Question 1: What suffix is used in the names of esters?
a) -ol
b) -al
c) -ate
d) -one
Question 2: What catalyst is necessary for the esterification reaction to take place?
a) H2SO4
b) H2CO3
c) HCI
d) HNO3
Homework Answers
1)suffix is used in the names of esters is -oate.
2)Esters are produced when carboxylic acids are heated with alcohols in the presence of an acid catalyst. The catalyst is usually concentrated sulphuric acid. So (a) is the correct option.
